I am encountering a very weird problem.
I am running on Adrenalin 20.1.3 , in the global graphics settings I can enable Crossfire , but when I go to the game settings and I want to change the crossfire mode from lets say standard to 1x1 friendly ,the only option that shows up is disabled.
I ran Witcher 3 to see if crossfire is working at all , which it is.
The Problem started after I changed my Motherboard.
Windows is freshly installed.

On AMD Adrenalin 20.1.2 this work normally, but the newest drivers are more stable (specially GTA V and 3DMark).
3 updates after and this still a issue. Please, fix it AMD.
